(Elsevier Science Ireland Ltd, 2003) Ajaiyeoba, E. O.; Oladepo, O.; Fawole, O. l.; Bolaji, A. M.; Akinboye, D. O.; Ogundahunsi, O. A. T.; Falade, C. O.; Gbotosho, G. O.; Itiola, O. A.; Happi, T. C.; Ebong, O. O.; Ononiwu, I. M.; Osowole, O. S.; Oduola, O. O.; Ashidi, J. S.; Oduola, A. M. J.
The ethnographic study was conducted in two communities in Oyo state in Southwestern Nigeria. The study sites consisted of a rural and an urban local government area located in the tropical rain forest zone of Nigeria. The study was designed to obtain information on febrile illnesses and herbal remedies for treatment with the aim of identifying potential antimalarial drugs. The study revealed that fever is a general term for describing illnesses associated with elevated body temperature. The indigenous Yoruba ethnic population has categorized fever based on symptoms and causes. The present communication is the result of focus group discussion and semi-structured questionnaire administered to traditional healers, herb sellers, elders and mothers. This was on types of fevers, symptoms and causes of febrile illnesses. The investigation also included use of traditional herbs in the prevention and treatment of the illnesses in the two communities. A total 514 respondents were interviewed. This was made up of 266 (51.8%) from Atiba local government area (LGA), an urban centre while 248 (48.2%) respondents were interviewed from Itesiwaju LGA, a rural community. The LGAs are located in Oyo State of Nigeria. The respondents proffered 12 types of febrile illnesses in a multiple response answering system in Yoruba language. The most common ones (direct translation into English) were: yellow fever (39.1%), typhoid (34.8%), ordinary (28.8%), rainy season (20.8%) and headache (10.5%) fevers respectively. Perceived causes each of the febrile illnesses included stress, mosquito bites, unclean water, rains and over exposure to the sun. Methods of fever prevention were mainly with the use of herbal decoctions, powdered herbs, orthodox medications and maintenance of proper hygiene. Of a total or 112 different herbal remedies used in the treatment or the febrile illnesses compiled from the study, 25 recipes are presented. Recipes consisted of 2-7 ingredients. Oral decoctions (84%), oral powders (63%). use as soaps and creams (40%) in a multiple response system, were the most prevalent routes of administration of prepared herbs used in the treatment of the fevers. Boiling in water or alcohol was the most common method used in the preparation of the remedies. The four most frequently mentioned (multiple response system) plants in the Southwest ethnobotany for fevers were Azadirachta indica (87.5%). Mangifera indica (75.0%), Morinda lucida (68.8%) and Citrus medica (68.8%).
Evaluation of valuation of toxicity profile of an alkaloidal fraction of the stem bark of picralima nitida (fam. apocynaceae)
(The Haworth Press, Inc., 2004) Fakeye, T. O.; Awe, S. O.; Odelola, H. A.; Ola-Davies, O. E.; Itiola, O. A.; Obajuluwa, T.
Dermal and acute toxicity evaluation of the basic alkaloidal fraction of the stem bark of Picralima nitida, which has been shown to have pronounced activity against causative organisms of dermatomycosis in man, was carried out in animals. Acute intraperitoneal toxicity tests showed a dose-dependent toxicity. There was inflammation and necrosis of liver hepatocytes accompanied by reduction in neutrophilic count and a corresponding increase in lymphocytic count. There was no sign of reddening or irritation when applied into the eye conjunctiva. Dermal tests also showed that the fraction caused no sensitization, inflammation or death in the animal models used.
Nigerian antimalarial ethnomedicine 2: Ethnobotanica surveys of herbal remedies used in the treatment of febrile illnesses in the middle belt of Nigeria
(2002) Ajaiyeoba, E. O.; Osowole, O. S.; Oduola, O .O.; Ashidi, J. S.; Akinboye, D. O.; Gbotosho, G. O.; Falade, C. O.; Ogundahunsi, O. A. T.; Fawole, O. I.; Bolaji, O. M.; Falade, M. O.; Oladepo, O. O.; Itiola, O. A.; Oduola, A. M. J.
An ethnobotanical survey was conducted among residents of Gboko (urban) and Katsina Ala ( rural) local government areas in Benue state located in the middle belt of Nigeria. The Katsina-Ala and Gboko communities belong to the Tiv ethnic group. Documentation of the use of herbs as alternative in the treatment of fevers and identification of potential phytomedicines against malaria was done. Semi-structured questionnaires and focus group discussion guides were used to obtain information on description of febrile illness and utilization of herbal remedies for prevention and treatment. A total of 499 respondents comprising of mothers, fathers, community leaders/elders, herbs sellers and traditional healers were interviewed in the study. In the study, 9 types of febrile illnesses were proffered. The five most common type of febrile illnesses described were malaria (37.3%), yellow (28.8%), typhoid (27.3%), high fever (3.4%) and ordinary fever (0.5%). Perceived causes of febrile illness included mosquito bites, contamination of water and food, among others. Headache, general weakness, yellow coloration of eyes/uririe, elevated body temperature and diarrhoea, were the most common symptoms associated with febrile illnesses outlined by the respondents. Furthermore, malaria (81.5%) and high fever (57%) were reported to be common during the rainy season while typhoid (52%) is common during the dry season. Yellow fever was said to be non-dependent on season. Respondents believed children were more at risk of malaria compared with the other types of febrile illnesses mentioned. The respondents indicated that herbal recipes were effective treatment for Febrile illness. From the 105 recipes compiled, Azadirachto indica, Ficus thonningii, Annona senegalensis and Cymbopogon citratus were the most frequent herbs mentioned. Leaf (60.4%), was the most common part of plants used while boiling (92.5%), was frequently mentioned as method of herbal remedy preparation. The main route of administration of remedies mentioned was oral administration (97.9%). The study confirms the potential contribution of Phytomedicine to management of febrile illnesses, including malaria in the Tiv ethnomedicine.
Preliminary investigation on industrial properties of the olode-falansa pegmatite, southwestern Nigeria
(Bachudo science, 2004) Elueze, A.A.; Itiola, O. A.; Nton, M.E.
In olode-falansa area, which is part of the southwestern basement complex of Nigeria near Ibadan, the major rock types are granite gneiss, quartzite, mediun-grained granite and pegmatite. In particular, the pegmatites which occur as low-lying bodies, with a mineralogy dominated by pinkish-white microcline perthite, quartz, muscovite and plagioclase plus accessory constituents of garnet, beryl and tourmaline have been investigated for their distribution, physical, chemical and mineralogical characteristics in order to evaluate their industrial qualities. Chemical analysis shows variations in the major elements contents of the main minerals. In particular, quarta samples have 64.02 to 97.30% SiO2; 0.86 to 2.60% Ai2O3, 0.05 to 1.02% K2O and 0.13 to 1.29% Fe2O3 while the feldspar samples are61.37 to 67.83% SiO2; 16.85 to 18.40% AI2O; 11.35 to 14.32% K2O and 0.04 to 0.11% Fe2O3 respectively. The total alkalis (Na2O+k2O) indicate k-feldspar composition. The specific gravity for quartz ranges from 2.60-2.63, while that of feldspar is from 2.55-2.58. Water absorption capacity is higher for quartz (25.10-27.10%) than feldspar (4.61-5.80%). Compressive strength of selected pegmatite minerals indidcates values from 133.24 to 223.84MN/m2. The investigation shows that the pegmatites have good potential for industrial uses. They can be used directly as raw materials or after beneficiation. In particular, the quartz and feldspar can find application in the refractory, glass, ceramic and abrasive industries. They can also be found useful in minor construction works especially in homes and offices. Muscovite can be used as thermal and electrical insulators while the beryl can be useful as ornaments. The associated rocks such as gneisses, quartzites and granites can be useful in interior and exterior decorations as well as tiles manufacturing.
